Can the USB port on the Airport Express power a 2.5" hard drive? Was thinking of buying a USB 'only-power' adapter cable since I get funky behavior from the Ethernet attached drive receiving data signals, but maybe there is no point.
Got a tip for us?

Hm... I don't want to mount the drive, just power it. This thread claims 5V 40mA output, is it enough for a 2,5" drive?

How is the drive powered now? Surely not over Ethernet. If you have an external power adapter and it isn't working, I'm guessing either the adapter has a problem or it wouldn't work via USB power, either. (I don't think there are a lot of 2.5" enclosures with external power supplies, so I'm curious how this is set up now.)
40ma would not be enough. The original USB spec was 500ma, and at the time, that was marginal to drive a HDD. I think (but have not checked) that newer versions of USB allow higher current.

It's got a built-in battery (http://www.macally.com/EN/?page_id=12507), but when it runs out I have to power it up through USB.
